--------------------------------------------------
1. Overview
--------------------------------------------------

This replication package reproduces all empirical results
reported in the paper, including:

- Main regression tables 
- Inequality interaction models
- Marginal effects figure
- Robustness checks and appendix tables (Tables A.1–A.8)

The analysis uses a fixed-effects panel of countries observed
over non-overlapping five-year periods and focuses on the
interaction between human capital and income inequality in
explaining economic growth.

--------------------------------------------------
2. Software Requirements
--------------------------------------------------

- Stata version 17 or higher
- Requires the user-written Stata command wbopendata, which can be installed via ssc install wbopendata.
- No other user-written commands are required
  (all estimation uses built-in Stata commands)

--------------------------------------------------
3. Folder Structure
--------------------------------------------------

The replication package assumes the following structure:

ROOT/
├── data/
│   ├── raw/        Original data files (as obtained from sources)
│   └── clean/      Intermediate datasets generated by the do-file
├── output/
│   ├── tables/     Regression tables
│   └── figures/    Figures and graphs
└── do/
    └── replication.do

All paths in the do-file are defined relative to ROOT.

--------------------------------------------------
4. How to Replicate the Results
--------------------------------------------------

1. Set the working directory in Stata to the project ROOT folder.
2. Open Stata.
3. Run the replication do-file from start to finish:

   do do/replication.do

All tables and figures will be generated automatically in
the output/ folder.
The output/ folder contains tables and figures generated by the replication do-file and is included for reference only.
--------------------------------------------------
5. Data Sources
--------------------------------------------------

- Barro–Lee Educational Attainment Dataset
- World Development Indicators (World Bank)
- Standardized World Income Inequality Database (SWIID)
- Additional learning-based human capital measures as described
  in the paper

All data transformations are documented in the replication do-file.
These data are all publicly available. They can also be accessed in the path /ROOT/data/raw

--------------------------------------------------
6. Notes
--------------------------------------------------

- The analysis uses real GDP per capita in constant (2015 USD) prices.
- All explanatory variables are lagged one five-year period relative to the growth outcome.
